AI Thread Summary
The discussion emphasizes the importance of evaluating laboratory equipment, particularly chromatography columns, to enhance problem-solving capabilities and expand laboratory versatility. Two main companies are highlighted: GE, known for its XK columns, which are popular due to their affordability and ease of maintenance but lack versatility and have issues with end fittings and frit design. In contrast, Essential Life Solutions offers Econoline columns featuring a true frit design and user-friendly screw-on end fittings, although they do not provide pre-packed options and are from a smaller company. The conversation encourages sharing insights on various chromatography products and their competitors to facilitate informed decisions in laboratory settings.

I think that it is essential for us to take a look at all the equipment that makes it easy for us to solve all the problems that we solve, in the laboratory setting. It helps us look at different products, help get reviews from our fellow scientists and to expand our laboratory's versatility.

I will start out by talking about 2 common companies that develop and sell chromatography columns. Feel free to add in about any chromatography product and its competitors and how they are better / worse than the other.

GE - XK Columns
PROS
​
Probably the most widely used columns in Chromatography right now.​
They are relatively cheap and are easy to use/ maintain​
They have a large company backing so the product is generally good quality​
Come packed or empty for convenience​
CONS
The product lacks versatility​
End Fittings are hard to remove​
Frits are not true frits, they are a sock design​

Essential Life Solutions - Econoline Columns
PROS
True Frit Design with dispersion mechanism​
End Fittings are "screw on/off" so it makes it easy to remove​
Double piston design and Aqueous or Solvent Resisten​
CONS
Do not come in with a packed column option​
Smaller company, but has good customer service​
Screwing mechanism can be tought after a long run​

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
